well, it's "nice" to see im not the only one with the gpu problem around... i have a HP z820 with:-2 Xeon e5-2640v2-32gigs ram-Cuadro k4000-declink 4k BM display card-cubix xpander with 3 titan black 8gigs each 18g total -SSD OS win 10-Davinci STUDIO

i've been working with no problems until davinci 14 with a lot of nodes in the projects NR included and never had this issue ... now im struggling every time i try to open one of those projects. ive done clean install, transcoded clips, the OS is perfect... the 3 titans never reach to work at 100% and suddenly i get the "your gpu memory is full" error

I had the same problem upgrading to v15. I have three nvidia 1080ti’s, 12gb a piece, in a Cubix Xpander. After I moved up resolve versions ‘gpu full’ was a constant on 5k red footage playing back in 4k timeline. My solution was to remove one of the gpu cards, leaving two in the xpander and the red rocket x in the pc. No more errors and playback was flawless whereas before having three cards slowed everything to much lower frame rates. I will continue to experiment.

Wondering if the new nvidia drivers helped as well. Saw a memory leak issue fixed mentioned on Windows somewhere...

I've had this same experience with 2x 1080 Ti, removing one tends to make 4K timelines and heavy TNR more stable. Must be something with how memory is swapped between cards with limited VRAM?

We recently upgraded to a single RTX Titan as a test - it's not as fast as 2x 1080 Ti but it doesn't get the memory full errors and can deal with an absurd amount of TNR at 4K (10x 5 frame Better TNR on 8K R3Ds at Full Premium. Whyyy does it work?).

I understand memory limitations but I wish Resolve was a little more graceful handling these exceptions.

The new drivers didn’t help, seemingly as I was already using them when I upgraded to V15 of Resolve. The other issue, I suspect is the cooling of the Cubix Xpander. A bigger fan wouldn’t go amiss to ensure gpu stability.

Will have to look at the RTX Titans. Sound promising for a future gpu upgrade.

Radeon VII is only $700 and has the same or more speed than the $2500 RTX Titan.The 16 GB is enough for doing 8k work (effects + TNR) atleast on our VEGA FE's.Radeon VII is faster because of the memory bandwidth (1024 GByte/sec).

Some gamers will be happy to buy your old 1080ti's for a good price.

ps. Radeon VII can make use of the HBCC so you will never run out of memory.
